Thus we estimate the number of Drell Yan events in region $D'$ to |
86 |
|
be $0.36\pm 0.36$. |

We also perform the DY estimate in the region $A'$. Here we find |
89 |

$N^{A'}(ee+\mu\mu)=5$, $N^{A'}(e\mu)=0$, |
90 |
+ |
$R^{D'}_{out/in}=0.50\pm0.43$ (stat.), giving an estimated |
91 |
+ |
number of Drell Yan events in region $A'$ to |
92 |
+ |
be $2.5 \pm 2.4$. |

This Drell Yan method could also be used to estimate |
96 |
|
the number of DY events in the signal region (region $D$). |

However, there is not enough statistics in the Monte |
161 |
|
by FR/(1-FR) where FR is the ``fake rate'' for the |
162 |

fakeable object. {\color{red} \bf The results are...} |
